Question about Sanyo DS27930 27" TV

2 Answers

Sanyo DSC27930 No picture, no sound but seems to have power.

My wife and daughter were watching TV recently when they heard a pop or crack like sound then suddenly there was no picture and no sound. Naturally the warranty had already expired....two years ago. Local repair shops want $150 to $300 to look at and or repair the thing. That is not practical for us seeing how the TV is almot four years old. We can't afford one of the newer flat TV's on the market now either. So, I pulled the back off the TV but did not see anything obviously wrong. Even the fuse looks okay. I was careful not to touch certain things and have done nothing to the TV so far. I'm thinking of trying the get a new fuse at Radio Shack, though I don't know if that will get the TV working again. Anyways what went wrong with it and can I fix it without it costing too much?
Thanks.

    I had a frined check out the fuse to day. I forgot what electronic tool he used but it showed the fuse to be good. Besides the fuse does not look blown. So, I guess the fuse is not the problem. Right?

    Hi,

    Thanks. I have checked for damaged, burnt or loose parts. I saw nothing burnt, or damaged to my knowledege and nothing was loose.

    Could be something messed up that is not obvious? Or, what else might be causing the TV problem?

Hi there!

My guess would be that you had a surge on the mains power. check for damaged or burnt parts in the power supply and or Line Stage. sometimes transistors and/or IC's can blow off a piece of the package. So check those as well. I do not have any info on this model but the specs are pretty much the same as any other Tube TV. Regards and good luck, JUS004

Hi there!

Something did Pop and yes it will cost 150 - $300 to repair. The question is what would a new unit of the same size and quality cost. If the repair is about a third of the cost of a new unit , it would still be considered economical in RSA. If repaired it may run again for another 4 years so the Math speaks for itself. The decision entirely yours in the end. It could really be anything that popped so to give advice would be difficult. However, try the fuse first. It is certainly the cheapest option at the moment. Regards and good luck, JUS004

    Hi there!

    This will then require skilled labour to measure and determine which part went faulty. Blown parts are not always obvious so they have to be found with test instruments like a multimeter and then one has to know how to measure the different components. Unfortunately I can't assist any further. Perhaps if I was closer. Regards and good luck, Jus004

A popping sound as you describe sounds as if your tv blew a couple capicators on the main control board. More than likely , you are needing to aquire a new main circuit board.

I was watching my Hitachi 42hdm12 and heard a pop and now the picture won't show up or sound or anything?


A pop is usually a power surge and you blew a board. If you take the tv apart, if this is it, it will be evident by the burn marks. You could have burned out the internal power supply as well.

Your lamp has blown. Time to get a new one.
